Garmin Nuvi 360 handlebar mount?

I bought my wife a Garmin Nuvi 360 GPS and she's been really happy with it, navigating around Boston and environs.

But it is so small and light (4"x3"x1", 5 ounces) and has such a great screen that it would be spectacular as a bike GPS. Except there's no mount. The RAM motorcycle mount is mighty bulky, and about $40.

Anyone cobble something together? Setting something up with the stock suction cup mount is possible but there must be a more elegant solution.

I've run into a similar problem as far as gps mounting goes. I have a Garmin c330, I5, and an I3, All of which I love but none of which seem robust enough to withstand bicycle vibrations and being exposed to the elements. The devices made for otorcycles are tough and waterproof but expensive! So I looked and researched and I think I've found the perfect solution- Mapping handhelds from Garmin ie eTrex or Rino or one of those. They are made for hiking, are waterproof and shock proof and you can actually buy a bike mount for them! Im loading maps into my eTrex Venture CX right now.
